The difference between solid tantalum capacitors and non solid tantalum capacitors 1

Solid tantalum capacitors and non solid tantalum capacitors are two important types of capacitors in the field of electronics, with significant differences in materials, construction, performance, and applications. This article will delve into the characteristics of these two types of capacitors to help understand their main differences.diode

1、 Basic concepts

Solid tantalum capacitor:

Solid tantalum capacitor is an AD9884AKS-100 capacitor that uses tantalum as the anode material and solid conductive polymer or manganese oxide as the cathode material. This type of capacitor is widely used in high demand fields such as military, aviation, medical, and communication due to its excellent performance.diode

Non solid tantalum capacitors:

Non solid tantalum capacitors typically refer to tantalum capacitors that use liquid electrolytes (such as sulfuric acid solution) as cathode materials. Compared to solid tantalum capacitors, non solid tantalum capacitors have more advantages in manufacturing costs, but are slightly inferior in certain performance indicators.diode

2、 Differences in construction and materials

Solid tantalum capacitors are formed by pressing and sintering tantalum powder to form a porous tantalum block as the anode. Then, a very thin layer of tantalum pentoxide is grown on the surface of the tantalum block as the dielectric layer. Finally, conductive polymers or manganates are used as solid cathode materials.diode
